Look at this gem I found in the heart of O'Fallon! This extra large lot and adorable home has so many possibilities! Come take a look and envision your future. An immaculate, well maintained, fully furnished, freshly painted home is waiting for YOU! Complete with all kitchen and laundry appliances too. Additionally there is a nice, big 8x12 exterior shed. Home Passed City Occupancy! Some ideas worth thinking about: You could build a new home on this lot and use the 1 bed, 1 bath as an office or gym or man cave/she shed. Think about this though, after building that new home.. now you have another home to house a relative and keep them close - A young adult, a parent, grandparent or friend. Or how about this: Maybe you have lots of toys! 4-wheeler, side by side, trailer, extra cars, motorcycle - you name it! Plenty of room to build a large garage to house them too. Close to schools, shops, parks, restaurants - everything you need! Highly desired O'Fallon Schools! #PantherPride #OTHS
